Ant Liquid Feeder for Test tubes

Very simple, yet works like a charm. If you don't have the specific bottles for these feeders, then this model will save your colony hungry for sugarwater!Made for Test tubes with the outside diameter of about 16,5 mm/0.65 in at their open end.I use these from BENU.Two types:Standard fits the test tube.Slope decreases in diameter towards the bottom. From 17,5 mm/0.69 in at the top down to 16,45 mm/0.65 in at the protrusions.The slope type is better for more various test tubes, since not all test tubes will fit the standard.Don't forget to turn on scarf seam.Post photos with your ants enjoying their new feeder!If you want a version for your testtubes, tell me the outside diameter of the open end!You can support me by boosting this model or by buying something from my Etsy: CzechOutAnts.
